摘要
该文将电力电子电路视为一类混杂动态系统,尝试在DC-DC变换器控制系统研究中引入切换线性系统的概念和理论。将基本DC-DC变换器建立为切换线性模型,由此提出DC-DC变换器能控性和能达性等基本控制特性,为DC-DC变换器控制系统的优化控制和其它控制策略的实现提供理论依据。以Buck变换器控制系统设计为例进行仿真验证,分析了能控性和能达性研究的理论意义。该文的研究还表明,研究方法也适应于其它电力电子电路能控性和能达性的研究。
In this paper, power electronic circuits were considered as one type hybrid dynamic systems and the concept and theory of switched linear systems were introduced to DC-DC converter control systems. Basic DC-DC converters were built as switched linear system models and the basic control characteristics, such as controllability and reachability, were presented which provided the basics of optimal control and other control methods in DC-DC converters. Simulation verification of Buck converter was given as an example to illustrate the theoretical meaning of controllability and reachability study. The research method could be used to study the controllability and reachability of other power electronic control systems.
